As Akari's summer break has finally begun, she wracks her brain to come up with fun, summery things she can do together with Sophie.
However, the ocean or anything outside are all a bad fit for a vampire like Sophie.
Then she has a moment of clarity and realized that a firework festival is at night and a summery activity, so she immediately begins preparing yukata.
Erie and Hinata and join them to go to the festival, however...
They vanish in an instant, but they'll 
stay in our memories forever.
،صحيح أنّها تختفي في لحظة
.لكنها تظلّ في ذاكرتنا إلى الأبد
Selbst wenn sie in nur einem Augenblick verschwinden,
bleiben sie für immer in den Erinnerungen verankert.
Desaparecen al instante, pero se quedan
siempre en nuestros recuerdos.
Desaparecen al instante, pero se quedan
siempre en nuestros recuerdos.
Même si ça dure qu’un instant,
ça reste à jamais dans nos souvenirs.
Anche se scompaiono in un attimo,
 rimarranno impressi per sempre nei nostri ricordi.
Eles desaparecem num instante,
mas ficarão nas nossas memórias para sempre.
Они исчезают вмиг, но 
в воспоминаниях остаются навеки.
